Contest University Celebrates 100 Years of Yagis |
|
The Yagi-Uda beam antenna was invented 100 years ago, in 1926, and Contest University (CTU) is celebrating its centennial with a live Zoom webinar this Saturday, September 19, 2026, at 1600 UTC (noon Eastern). The free webinar, titled “The Yagi Turns 100,” will be presented by Greg Ordy, W8WWV, and will be available online at w3lif.org/yagi. Ordy will walk through the history of this amazing antenna that has been a mainstay of amateur radio DXing and contesting for a century.
There is no pre-registration for this event.
Click on the link (above) before 1600 Zulu on Saturday to watch.
Contest University Chairman Tim Duffy, K3LR, and Scott Jones, N3RA, will be monitoring the chat during the presentation and will relay questions from viewers to Ordy at the conclusion of his talk.
Duffy says the webinar will be recorded, and the recorded link will be posted on the CTU website
next week.

WRTC 2026 Organizers Honored by FOC |
|
The First Class CW Operators’ Club (FOC) has awarded its highest honor, the Al Slater, G3FXB (SK), Memorial Award, to the World Radiosport Team Championship 2026 (WRTC 2026) Organizing Committee in recognition of its work not only in planning and executing last July’s competition, but also in its response to allegations of cheating by some participants.
FOC President John Warburton, G4IRN, said the award recognizes an individual, group, or organization “whose contribution to amateur radio reflects the qualities that Al embodied throughout his life: operating excellence, friendship, encouragement of others, and service to the hobby.”
According to a report in The Daily DX, Warburton said FOC determined that the WRTC committee “demonstrated those qualities on an exceptional scale, [creating] an environment that showcases the very highest standards of amateur radio operating, rewarding skill, fairness, technical competence, and ethical conduct.” He added that “the judging committee’s careful verification work ensured that these standards were upheld and that the results reflected the true performance of those who competed within the rules.” This was a reference to the Organizing Committee’s recent announcement that several stations, including the original winner, had been disqualified due to rule violations discovered after the contest.
The award was presented at FOC’s annual gala dinner on September 12 in Cheshire, England.

Get Ready for Jamboree on the Air |
|
“We've got scouts, we've got a special event call sign, and we'd love as many hams as possible — near and far — to come find us on the air.” That’s how Sal Mancuso, W6SAL, is promoting Jamboree on the Air (JOTA) 2026 on behalf of the Silicon Valley Monterey Bay Council of Scouting America (formerly Boy Scouts of America). JOTA is an annual worldwide event, on the air and on the internet (as JOTI), with the goal of promoting friendship and global citizenship via amateur radio and the internet.
This year’s event will be held from October 16-18, and now is a good time for radio clubs and individual hams to reach out to local scout units to set up JOTA experiences.
For Mancuso, it has meant getting a special event call sign — K6S — and setting up a public demonstration station on October 17 for scouts from throughout the Silicon Valley Monterey Bay Council. The council serves 10,000 youth across Monterey, San Benito, Santa Clara, and Santa Cruz counties in California. “We'll have approximately seven licensed operators of varying license classes (Technician through Extra) on hand, running HF, VHF, and UHF simultaneously, all signing K6S,” explains Mancuso. “Scouts will be hands-on at the mic and keyboard the whole time — this is their event, not just something they're watching … We'll be active on HF SSB and FT8, with packet possible as well.” Planned HF SSB frequencies are 7.090, 14.290, 18.140, and 28.990 MHz, but Mancuso noted that “We'll also be posting our actual live frequencies on Spotted Hams
as the day goes, since real-world band conditions may shift our plan a bit.”
More information on setting up a JOTA/JOTI operation may be found at www.jotajoti.info. ARRL has resources to assist volunteers who are working with scouts, including a flyer promoting Radio Communications for Scouts
(PDF) and the ARRL Radio and Wireless Technology Patch Program. For additional ideas, visit www.arrl.org/amateur-radio-and-scouting.

On the Air LIVE
Join ARRL Director for Learning and Education Wayne Greene, KB4DSF, for the September episode of OTA Live on Tuesday, September 22 at 8 PM Eastern, where he will explore an inexpensive and practical way to evaluate the performance of your handheld (HT) radio. Using a low-cost Software Defined Radio (SDR) dongle, free SDR software, and free audio-editing software, Wayne will demonstrate several tests that can help you get a better idea of how well your HT is working. While these measurements won’t replace lab-grade testing, they can reveal useful information about your radio’s performance. Wayne will also demonstrate how to use these tools to identify CTCSS tones and DCS codes. The livestream will air on the ARRL's learning center, learn.arrl.org. Preregistration is required and can be accomplished through the Learning Center.

Solar image on September 17, 2026 [Photo courtesy NOAA Space Weather Prediction Center] | | |
Solar flare activity is expected to remain at very low levels, with a chance for isolated C-class flares through September 19, according to NOAA’s Space Weather Prediction Center (SWPC). Solar wind speed was steady near 530 km/s, and negative polarity CH HSS (coronal hole high-speed stream) effects are anticipated to persist through September 18, with additional enhancements likely today due to flanking influences from CMEs (coronal mass ejections) that departed the Sun on September 13 and 14. Geomagnetic activity is expected to reach active to G1 (minor) storm levels today due to combined CH and CME influences.
Unsettled to active conditions are likely on September 18-19 as enhancements wane.
The Australian Space Weather Forecasting Centre reports that there are currently three numbered sunspot regions on the solar disk, and that all three are stable.
No flares are expected over the next several days.
The global HF propagation forecast for middle latitudes is normal to fair today, followed by normal propagation in the days that follow.
Predicted 10.7-centimeter radio flux from the SWPC: Sep 17, 93; Sep 18-19, 90; Sep 20, 95; Sep 21, 100; Sep 22, 110; Sep 23, 105.
Send your tips, questions, or comments to w2vu@arrl.org.

the ARRL Technical Information Service, read
"What the Numbers Mean...," and check out

is available. For customizable propagation charts, visit the VOACAP Online for Ham Radio
